A student wants to show the transfer of heat energy without matter. Which investigation design would best help the student?
a
an investigation of radiation through a current in a fluid
b
an investigation of radiation through electromagnetic waves
c
an investigation of conduction through the movement of particles through a solid
d
an investigation of conduction through collisions between particles in space
b
an investigation of radiation through electromagnetic waves
The investigation design that would best help the student show the transfer of heat energy without matter is option b - an investigation of radiation through electromagnetic waves. Radiation is the transfer of heat energy through electromagnetic waves, such as light or infrared radiation, and it does not require a medium (matter) to transfer heat. Therefore, this design would allow the student to demonstrate heat transfer without the need for matter.
To show the transfer of heat energy without matter, the student can focus on investigating radiation, as radiation involves the transfer of energy in the form of electromagnetic waves. This eliminates options C and D, which involve the movement of particles through a solid or in space, respectively.
Among the remaining options, A and B, the investigation of radiation through electromagnetic waves (option B) would be the best choice. This is because electromagnetic waves, such as light or heat from the Sun, can travel through vacuum, which means they can transfer energy without the need for a medium or matter. Option A involves radiation through a current in a fluid, which implies the presence of matter, unlike radiation through electromagnetic waves.
Therefore, option B, an investigation of radiation through electromagnetic waves, would best help the student show the transfer of heat energy without matter.
